I certainly was not disappointed with Grave Digger. They pretty much were the last "have to see before they hang it up" band on my bucket list. Of course I wish they played longer, but they had a good mix of stuff. Like Bob said, vocals were a little low audio wise, but it wasn't horrible as I only really noticed it when the audience was clapping along. As for BG. They were good, but they also just aren't my favorite band in the world. Hansi's voice wasn't perfect, but with his style it isn't as noticeable as say if Fabio's voice was shot. That said, I think it's odd you'd do a 2 hour set if you have a cold which has been speculated. Between this and the last tour though, I probably don't have to see them again unless they have a great support act again.
